p SPECIFICATION forming part of Letters Patent No. 568,003, datedSeptember 22, 1896. Application filed February 14, 1896.41 `Serial llo.579,276. l (No model.) l

To all w21/0m it nea/y concern: A

Be it known that I, JOHN W. SHIRER, residing at Pittsburg, in thecountyof Allegheny and State of Pennsylvania, have invented a new andImproved Roofing-Bracket, of which the following is a specification.

My invention is in the nature'of a roofingbracket, more especiallyadapted for slaters use, and it primarily has for its object to providea bracket of this kind of a simple and inexpensive construction, whichcan be easily placed in position, and which will effectively serve forits intended purposes.

My invention also has .for its object to provide a bracket for thepurpose stated of such a weight andsize that one slater can readilycarry a sufficient number to put on any ordinar f-sized roof.

Furthermore, my invention has for its object to provide a slater-sbracket which can be quickly and detachably held secure on the roof andwhich can be almost instantly detached without the use of ropes or othersupporting means and without interfering with the continuous operationvof placing the courses of slate on the'sheathing.

Vith other minor objects in view, which will appear hereinafter, theinvention consists in the peculiar combination and novel arrangement ofparts, such as first described in detail, and then specifically pointedout in the appended claim, reference'being had to the accompanyingdrawings, in which- Figure l illustrates myinvention as applied for use.Fig. 2 is a perspective View of one of the brackets. Fig. 3 is alongitudinal section of the same, taken on the line 3 `3 of Fig. 4. Fig.4 is a face View of the bracket, illustrating the manner in which it isheld on the supporting-nail; and Fig. 5 is a perspective view of thebracket folded. y

My improved bracket is made of steel and comprises a flat bar A, whichforms the base of the bracket and which is preferably threesixteenths ofan inch thick and one and onequarter inches wide, its lower end beingspread or widened, as at a c, to provide a good bearingsurface at suchend, while the upper endhas an upwardlyinclined slot B at one edgewhereby to provide a hook member C for a purpose presently explained. v

Projected up from the barA are apertured jears D D, towhich arepivotally joined the supporting-bars E and F by the rivets e and f. ThebarE, which when extended forms ahorizontal rest for the scaffold-boardG, has asingle aperture c in its outer end, while' the bar F, whichforlns the diagonal brace, has a number of apertures flV f to providefor a proper adjustment of the bar E on roofs of different pitch. Byjoining the bars E and F in the manner shown and described it ismanifest that the same can be folded down against the bar or basememberA, and thereby admit of a number of the said brackets beingcompactly held together and in convenient form to be carried by theslater.

The manner in which my improvement is used is best explained as follows:After the roof has been slated as far as can be conveniently done fromthe roof ledgelorgutter a twenty-penny nail is driven inthe sheathing ata point just above the last slate course and through the slot in thehook end of the member A. A similar nail is driven ata suitabledistance, say about eight feet, away and a second bracket hung thereon.The members E and F are then opened toa proper position by means of abolt or pin H, passed through the aperture e in the member E and thedesired one of the apertures in the member F, it being manifest t-hat,if desired, the said bolt I-I may have a suitable keeper-to hold it fromaccidental displacement. brackets are thus set the board I is placedtherein; The scaffold is then ready for the slaters. After the slating4reaches a point above the scaffold too high for further working from thesaid scaffold a second scaffolding is put up as before. it should bestated that the bracket-holding nails are driven sufficiently close toallow the next course of slate above it to lap over same. It will thusbe seen that when it is desired to remove the brackets all that isnecessary is to push the bracket up a short distance between the slateand then turn it to the right or left to disengage it from the nail,after which it can be easily pulled out from und er the slate, It willbeobserved by reference to Fig. 2 that the member 4E is pivoted to thebase A in such a manner as to leave an upper extension A', adapted topermit the first slate course to be lapped over the same, as shown.

After the` IOO By providing a bracket constructed as described I am ableto put up a scaffold ninety feet long and have the slaters at WorkWithin ve minutes. Furthermore, as no twisting or holding ropes are usedthere will be nothing to interfere With the proper placing of a paperlining over the sheathing previous to putting on the slate, it beingmanifest that as a second scaffold can be quickly put in place by theslater as he stands on the rst, he can also quickly transfer any slateheld on the rst scaffold to the second in a very little time.

Other advantages of my invention Will readily appear to those skilled inthe art to Which it appertains.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

A scaffold-bracket comprising a at base-i JOHN W. SHIRER.
